...electricity passing through a wire, parallel with and near to a freely suspended magnetic needle, deflected the needle to the right or to the left, according to the direction of the current. Professor Schweiger, of Halle, very soon after invented the wire-coil, or Electro-magnetic multiplier,... | |
